Today in the experimental installation of Oracle 12c, when creating a database of being given the wrong information is as follows:
ORA-00821: Specified value of sga_target 384M is too small, needs to be at least 396M
Obviously, sga_target parameter setting errors, greater than 396M
This error makes me think before I choose where to allocate memory using Automatic Shared Memory Management tune settings:
I can only abort the installation database, and re-run the installation data manipulations, large distribution point in allocating memory in 396M over here sga can see personal configuration environment situation, I am here is because his environment is relatively small, then use it to set the size of the prompt. So before that last step you want to install a database to some previous parameter settings in place.
If this is the error when starting Oracle, that solution:
1. Log sqlplus (as sysdba), and then generates spfile -> create spfile from pfile.
2. Find spfile ([oracle_home] / database / init [SID] .ora), modified sga_target = 368M
3.startup
